In this paper, we investigate a sample of Tencent QQ online social network and analyze in detail the users＇ basic characteristics, users＇ behavior patterns of making friends and chatting, and the users＇ geographical distribution. In addition, comparing with an authoritative data acquired from China City Statistical Yearbook, we find positive correlations between the regional development indicators and the characteristics of online social networks, such as the number of online users, the total chatting days of a city. This indicates that users＇ behaviors in online social networks could reflect the development of local economy, transport, telecommunications, etc. Our findings are instructive for regional economic research.
